You can tell I use my “half sheet pans” every day….I’d say they are well “broken in”, as they certainly are a workhorse in our kitchen.  I love having lots of them so I can always grab a clean one….line it with a pre-cut parchment sheet and I am ready to go for roasting veggies, baking cauli rice…so handy!  These are made of aluminum…and I am not a fan of that…BUT I always line them with parchment or a silpat so food is never in direct contact with the aluminum.  The restaurant grade ones are almost always aluminum for its light weight and heat conductivity.

I also love my smaller ones (quarter and eighth), which are great for fish en papillote or for re-heating smaller items in the oven, and the eighth size even fits in my “Breville Smart Oven” Toaster.

We buy our “half sheets” from a local restaurant supply store, but they are available online. I bought the quarter and eighth sheet pans on amazon.com.
